Standard room/corner fire test is a full-scale reaction-to-fire research method. It's mainly used to evaluate lining materials on enclosure. This paper introduces the principles and experimental devices of ISO 9705 room/corner fire test, and describes the progress in study on fire behavior of linings, which is under this method，including the researches of lining materials' HRR (Heat Release Rate)，RSP (Rate of Smoke Production) and surface flame spread process. Furthermore, the application of results on the classification and fire hazard evaluation of lining materials is analyzed. At last of this paper, some future work in this field is ponited out.
